MIAMI (CBS4)- It’s important to exercise our bodies, but what about our brains? Researchers say there’s science behind the brain train phenomenon, and working out the brain is becoming big business.

While it may look like “brain trainer” Laura Brumberg is exercising her arms and legs, it’s her brain that she’s really working out.

“It takes a few minutes and it allows for focus and concentration,” Brumberg said.

Brumberg is part of a worldwide fitness revolution called “brain training.”

The burgeoning industry includes everything from computer based programs to actual brain gyms where consumers build mental functions the same way they build muscles.

“So it could be just as simple as balancing your checkbook or organizing your house,” said Mary Meoshi, a brain trainer.

She teaches a series of physical movements that are said to stimulate different areas of the brain to help increase mental performance.

“As you start to do these developmental movements, more neuro connections are made between all the parts of the brain,” Meoshi said.

Physical trainer Brant Omuseman is used to working out his body and is now a firm believer of also working out his brain.

“There are different parts of our brains and we tend to hang out in certain parts and this allows us more access to more parts more often,” he said.

Brumberg said he benefited from working out his brain.

“I learned some activities that I couldn’t do before presentation just to improve my focus and to allow me to be in a more relaxed place,” Brumberg said.

Brain training games are also growing in popularity, especially at the workplace.

“I thought it would be useful for professionals, many of whom are over 50 to have their brains tuned up a little bit,” said Howard, Chief Executive Officer at a venture capital firm, and also a brain trainer.

He said the computer games have helped to improve his cognitive abilities. Howard said he hopes it benefits his employees too.
